Safetrack Impedance Bond provides continuity between railroad, or transit, track circuits for AC and DC propulsion current. These mechanisms also distribute propulsion between two running rails. Our Impedance Bond is made of insulated copper cable with low resistance.

On electrified railroads, impedance bonds are the most important component in railway signaling.

They are used on electrified railways to provide a continuous path around insulated joints for the return propulsion current and to confine the alternating-current signaling energy to its own track circuit.
